HDPE double-wall corrugated pipe is a new type of lightweight pipe with high-density polyethylene as the main raw material, the inner and outer layers are simultaneously extruded and formed at one time. The inner wall is smooth and flat, the outer wall is trapezoidal corrugated, and there is a hollow wall between the inner and outer walls. The unique wall structure design makes the tube have the characteristics of large ring stiffness, light weight, high pressure resistance, good toughness and corrosion resistance. It can be laid on the road with poor geology, and it has good sealing and quick construction.

Features

Anti-shock and anti-shock, good earthquake resistance, strong resistance to uneven foundation settlement;

Low friction and large flow;

Acid and alkali resistant, corrosion resistant, chemically stable;

Adaptable to environmental conditions, wide temperature range, especially suitable for laying in alpine regions;

Light weight, convenient for transportation, installation and maintenance;

Long life, buried laying life of more than 50 years;

Non-polluting, non-toxic, green and environmentally friendly products.
